REVERSIBLE FRICTION-GEARING.

Specification of Letters Patent.

Application filed October 28, 1911.

Patented June 3, 1913. Serial No. 657,302.

To all whom it may concern Be it known that I, JOHN A. WEBER, a citizenof the United States, residing at Toledo, in the county of Lucas andState of Ohio, have invented certain new and useful Improvements inReversible Friction-Gear ing; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

In saw mills in which reciprocating toothed bars are employed to turnthe logs on the log carriage, it is necessary to employ means forreversing the motion of the toothed bars, and it is desirable that thisshould be accomplished quickly and easily.

My invention is designed to furnish a gearing for the purpose indicated,and, more particularly, to provide a cheap, simple and effectivereversing friction gearing in which the shaft which communicates motionto the log turner may be caused, by a slight movement of controllingmechanism, to revolve in either direction. I attain these objects bymeans of the construction and arrangement of parts hereinafterdescribed, and shown and illustrated in the accompanying drawings, inwhich,

Fi ure 1 is a side-elevation of my device, and *ig. 2, an end-view ofthe same seen from the right in Fig. 1.

Like parts are indicated by like numerals of reference in both figures.

In the drawings, 1 is the shaft upon the end of which a circular saw ismounted or which drives any sort of saw, which shaft rotates constantlyin one direction. Upon this shaft is fixed a friction wheel 2. 3 is abase or frame which supports a boX 4, upon which is pivotally supportedthe lower end of an upright swinging arm 5. In this rockarm, near itslower end, is journaled, as at 6, one end of a shaft 7 which drives orcommunicates motion to the log turning mechanism. This shaft is somounted as to have a slight horizontal play at the end which isjournaled in the rock-arm. Upon the shaft 7 is fixed a friction pulley 8close to and in the same vertical plane with the friction wheel 2.

Copies of this patent may be obtained for A U-shaped member or stirrup 9has its lower extremities pivoted, as at 10, upon the shaft 7 onopposite sides of the pulley 8. To the top of the stirrup 9 is pivotallysecured a rod 11 leading to within convenient reach of the operator. Thetop of the rockarm 5 is connected by a stout cord or rod 12 with the rod11, as at 13.

14 is a friction pulley in close proximity to the pulleys 2 and 8,journaled as at 15 between two bars 16, of which but one appears in thedrawing. These bars are pivoted at their upper ends to the upper end ofthe stirrup 9 upon the same pin 17, which forms a pivot for the rod 11.The lower end of the bars 16 have a sliding support, as at 18, upon thesupporting frame 3.

When the rod 11 is drawn toward the operator, the rock-arm 5, throughthe cord 12, is caused to swing upon its pivotal support, bringing thefaces of the pulleys 2 and 8 into operative contact and causing theshaft 7 to revolve in the desired direction. When the rod 11 is pushedaway from the operator, the pull upon the rock-arm 5 is released and thepulley 8 moves out of 0011- tact with the pulley 2 as the pulley 1 1 isforced into frictional engagement with the pulleys 2 and 8, thusreversing the rotation of the pulley 8 and its shaft.

Having described my invention, what I claim and desire to secure byLetters Patent of the United States is,-

In a device of the described character, a driving friction-wheel, arock-arm, a friction-pulley, a shaft for the pulley having one endsupported in said rock-arm, a second friction-pulley mounted in closeproximity to the wheel and the pulley first mentioned, a movable supportfor said second pulley, arms pivotally supported upon said shaft, acontrolling rod pivotally connected with said arms, connections betweensaid rod and said rock-arm, and a pivotal connection between saidpulley-support and said arms.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN A. WEBER.
